Brazil says it has identified a suspected Ebola case who arrived in the country on Thursday.

The patient, Souleymane Bah from Guinea, presented himself after coming down with a fever at a public health centre in the town of Cascavel in the southern state of Parana.

He has been flown to Rio de Janeiro to the National Institute of Infectology.

Doctors say he no longer has a fever and blood test results are expected on Saturday.

Health Minister Arthur Chioro said the situation was under control and ?all health protocols and procedures were applied efficiently and with great success.?

Guinea is one of the three West African countries most affected by Ebola.

Bah?s symptoms appeared on the 20th day after he left Guinea ? within the 21-day incubation period.

But since his arrival, he has not shown any symptoms and his fever has not returned.

Bah arrived in Brazil as a refugee and was granted leave to remain until 2015 by immigration police.

Sixty-four people, who came into contact with Bah, mostly in the health centre in Parana, are also being monitored for symptoms of Ebola, although the Health Ministry says they are considered low risk.

Concerns have been expressed about what route Bah took to get to Brazil.

The authorities in Argentina are concerned he may have come to South America through one of the country?s airports or ports.

The Brazilian Health Ministry says it has contacted the World Health Organisation about these concerns.
